Sig Sauer
The Sig Sauer Picatinny to AR-Style Steel Stock Adapter is a conversion rail that bridges the gap between Picatinny-equipped firearms and standard AR-pattern stocks or stabilizing braces. Built from steel, this adapter lets you retrofit your setup with aftermarket components designed for the AR platform, expanding your configuration options without replacing your firearm's core receiver or rail system.
This adapter is particularly useful if you're running a Picatinny-railed platform—like certain Sig Sauer pistols or PDWs—and want to add an AR-compatible stock or brace. The steel construction delivers the durability and precision fit you'd expect from Sig Sauer, and the black finish matches most modern tactical setups. Whether you're building a pistol with a stabilizing brace or configuring a short-barreled rifle, this adapter gives you access to a much wider aftermarket ecosystem without compromising on quality or fit.
Installation is straightforward for anyone comfortable handling basic firearms assembly. The adapter mounts directly to your Picatinny rail and accepts standard AR-style stock interfaces, so you can choose the brace or stock that suits your ergonomics and mission. It's a smart solution for maximizing modularity on purpose-built platforms.
This adapter is designed for Picatinny-railed platforms. Check your firearm's rail configuration—if it features a standard Picatinny rail interface, this adapter should be compatible. If you're unsure, confirm your specific model accepts Picatinny accessories.
Any stock or brace with a standard AR-pattern mounting interface will work with this adapter. That opens up countless options from the aftermarket, so you can tailor your setup to your needs.
This adapter is designed for users with basic firearms assembly knowledge. If you're not comfortable installing it yourself, have a qualified gunsmith do the work to ensure proper fit and function.
